Objective:Explain how air resistance affects falling objects.
TechTerms: Air resistance: force that opposes the movement of an object in air Terminal velocity: speed at which air resistance and gravity acting on a falling object are equal Vacuum: empty space Anticipatory set: video and ask them what they know about air resistance.
Instructions: 1.View video and ask questions on what was seen about air resistance. 2.Do experiment- what falls faster? Split into 4 groups, each given 3 objects to test. 3.Write 2- to 3 sentences on what was learned about air resistance. 4.Tell about Vacuum. (see tech terms) 5.Do questions.
Guided Practice: Group experiment- What falls faster?
Closure: Quiz w/ optional question at end.
Assessment: Quiz.
Possible extension: Test other objects at home.
